In rabbits, short hair (S) is dominant over long hair (s). What genotype and phenotype ratios are expected from a cross between
irga5000 [103]

Answer:

Answer:

Genotype                  Phenotype                      

SS                 1/4          Short hair         3/4

Ss                 2/4         Short hair          3/4

ss                  1/4          Long hair          1/4

Explanation:

Both are heterozygous for the trait so we can expect that the cross would be:

Ss x Ss

   S     s

S  SS   Ss

s   Ss   ss

So the resulting off-spring would have the following genotype and phenotype:

1 out of 4 will have a genotype of SS.

2 out of 4 or half will have a genotype of Ss.

1 out of 4 will have a genotype of ss.

But because short hair is dominant the phenotype ratios would differ because Ss and SS would express short hair, so we add up their ration:

Short hair: 1/4 + 2/4 = 3/4

Long hair:  1/4

So in summary:

Genotype                  Phenotype                      

SS                 1/4          Short hair         3/4

Ss                 2/4         Short hair        

ss                  1/4          Long hair          1/4

If the dna content of a diploid cell in the g1 phase of the cell cycle is represented by x, then the dna content of the same cel
s2008m [1.1K]
Mitosis and meiosis are both cell division process except that the former is only done by somatic cells and the latter is done by gametes. In G1 phase or the growth phase of interphase, there is increase in cellular substance without DNA replication therefore DNA will be regarded as x. By the time when S or synthesis phase of interphase is finished, DNA replication is done therefore all phases that follow the S phase will have a DNA of 2x. In this case, the cell in metaphase of meiosis I has double the amount of DNA than the one in G1 phase because this cell already underwent the S phase. In meiosis, after the first division (meiosis I), there is reduction of genetic material into half (hence called reduction division) producing haploid cells. So a cell in the metaphase of meiosis II will have DNA half of that in metaphase of meiosis I thereby regarded as x.
